Bug 14693

We need to know what chip you have, and some way of reproducing this.  That excerpt of your log looks like the results of "we hung the chip, X exited, then X started up again and noted that something had gone wrong."  Maybe.  Please upload a whole log of the failure (might be in /var/log/Xorg.0.log.old instead of /var/log/Xorg.0.log if X did in fact exit when the problem first occurred and your server restarted) as a text attachment to this bug.

Please refer to http://www.intellinuxgraphics.org/how_to_report_bug.html to
provide sufficient info.

When it "freezes", network and keyboard don't work, right?

I've changed to version 2.1.1 and it is ok.
But here is the specifications:
Chipset: i945 (Intel 945GMA)
system arch: i686
xf86-video-intel: >= 2.2.0
xserver: 1.4.0.90
mesa: 7.0.3rc1
drm: 2.3.0
kernel version: 2.6.24-ARCH
distro: ArchLinux
Reproduce steps: Install the bugged version of driver and have the "luck" to freeze the machine.
Attachements: As I've changed to a old driver, the logs of the freezing had gone, but here: http://bugs.archlinux.org/task/8976 exists more logs of that problem.

Gordon Jin, the keyboard don't work, but I didn't tested the network.

It looks a regression from 2.1.1 driver. Could you help to git-bisect which commit might cause the problem?

Wang Zhenyu, since http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=commit;h=04b60b6d3436fb57163c23acf335364f0ea2f79c to 
it is bugged.

Are you sure you bisected correctly?  The change you pointed at is just a version bump, nothing in the driver was actually modified.  Or are you saying the very next commit caused the problem?

I am saying that since that version it started getting this freezes.

So it sounds like you didn't actually run the bisect...

But you have two versions, one good and one bad, so you can start the bisect process by doing 'git bisect start 04b60b6d3436fb57163c23acf335364f0ea2f79c 3c552af65d28fafec1d09484a8914b690b961349' then follow the directions from 'git help bisect' to narrow down the exact commit that broke things for you.

Thanks,
Jesse

Any news about this? Does system still freeze or any bisect result?

I can't debug this, because I use this: http://xorg.freedesktop.org/archive/individual/driver/xf86-video-intel-2.1.1.tar.gz

Any version after that is bugged.

Ok, since 2.1.1 works for you, can you build it directly from git and help us isolate where the bug actually started (it was between releases somewhere).

This should get you a working driver:
  $ git clone git://git.freedesktop.org/git/xorg/driver/xf86-video-intel
  $ cd xf86-video-intel
  $ git checkout xf86-video-intel-2.1.1
  $ ./autogen --exec-dir=/usr # and --libdir=/usr/lib64 if you're on x86_64
  $ make
  $ su -c "make install"

If that still works, then you can start looking for the problem:
  $ git checkout master
  $ git bisect start
  $ git bisect bad
  $ git bisect good xf86-video-intel-2.1.1

But my guess is that if you revert the patch in the next comment the latest tree might work for you.

Don't restore pipes unconditionally (should help some 855 users)

The --exec-dir doesn't exists.

Oops, I meant --exec-prefix, sorry.  There are better instructions here:

You'll need the X development headers & macros from your distro installed before the autogen & configure will work right.  Does your distro have those packaged?

Nop.

Alexandre, what's your laptop model? And we haven't seen any log files posted, pls attach your logs here.

Jesse, want me to test your patch on my GM855?

xorg log

Wang, look at the attachements, I've commented the files to explain when it happens, etc...

By the way, I have a HP Pavilion dv6128ea with Intel GMA 945

Alexandre, can you find the X log file that contains the crash information?  It may be called Xorg.0.log.old after the crash happens and gdm restarts X.

The attach xorg log is Xorg.0.log

Right, but it doesn't contain any crash information.  Since you're running gdm, X will just restart after a crash so the Xorg.0.log won't contain useful information.  Can you please attach your Xorg.0.log.old file after a crash happens?

*G*, tomorrow will do that.

The log is the same. :S

Ok...  Can you spend some time figuring out exactly what sequence of events causes the "blank screen" problem?  If you can find that, then maybe we can reproduce it on our side and find the problem...

It is "random", sometimes I am listening music with exaile, in xchat chatting, firefox opened and it crashes. Other times I am not with this all stuff opened...

Well, I think we'll need more info to track it down.  Either a series of steps that always causes the crash, or some useful logs of the crash...  There are some instructions at intellinuxgraphics.org and http://wiki.x.org/wiki/Development/Documentation/ServerDebugging that might help you capture some useful debug data...

Tracking this.. Having same trouble (or very alike) with latest git of intel driver. Looks like tough deal to bisect: many tags earlier than HEAD just do not build, and since I'm kernel chap, do not have alot of ideas how to hack-n-fix that.

So far, on my 

00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) (prog-if 00 [VGA controller])
	Subsystem: Hewlett-Packard Company NX6110/NC6120
	Flags: bus master, fast devsel, latency 0, IRQ 16
	Memory at d0400000 (32-bit, non-prefetchable) [size=512K]
	I/O ports at 7000 [size=8]
	Memory at c0000000 (32-bit, prefetchable) [size=256M]
	Memory at d0480000 (32-bit, non-prefetchable) [size=256K]
	Capabilities: [d0] Power Management version 2
	Kernel modules: intelfb, i915

I can start X only once. Switching to the console back and forth (may be fb console or normal - no difference) turns backlight off. IOW, one can still see login prompt from gdm if tries hard enough :)

Vitaly, that sounds like a different bug than this one.  Can you file a new bug for it with the info requested in http://www.intellinuxgraphics.org/how_to_report_bug.html?  I'm also curious what 'xrandr --prop' reports on your machine after starting up.  And please try to reproduce the problem without the intelfb (or any fb) drivers loaded too please.

Jesse, look at that:

Looks like the bug is fixed, thanks for the link!
